VS2015 Typescript compile to single file on save not working

This has been fixed.

Go to Extensions and Updates. Update to version 1.5.4 or above and it should work.

The upgrade process is a little odd because a new Visual Studio installer will appear on top of the current instance. Close the Visual Studio underneath and then continue with the update to avoid conflicts.

It took quite a surprising length of time (over a minute) to apply the update but it works fine now.

Note: When making a .ts file to then save change you must make a real code change, not just type something, delete it and save or it won't be recognized.

Yes, I reproduced this too
